2011-09-02Refactor CheckAddressOfOperand() by pulling out redundant code and moving ↵Richard Trieu

2011-09-02Always construct an ASTReader with a non-NULL ASTContext andDouglas Gregor
Preprocessor, eliminating the constructor that was used by ASTUnit (which didn't provide an ASTContext or Prepreprocessor). Ensuring that both objects are non-NULL will simplify module loading (but none of that is done yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138986 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact. No actual functionality change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138985 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Allow the preprocessor to be constructed without performing target-Douglas Gregor
and language-specific initialization. Use this to allow ASTUnit to create a preprocessor object *before* loading the AST file. No actual functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138983 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Refactor CheckAdditionOperands(), CheckSubtractionOperands(), and ↵Richard Trieu

2011-09-01Extend the self-reference warning to catch when a constructor references ↵Richard Trieu

2011-09-01Teach ASTContext and Preprocessor to hold on to references to the sameDouglas Gregor
LangOptions, rather than making distinct copies of LangOptions. Granted, LangOptions doesn't actually get modified, but this will eventually make it easier to construct ASTContext and Preprocessor before we know all of the LangOptions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138959 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-01Modules hide macro definitions by default, so that silly things likeDouglas Gregor
include guards don't show up as macro definitions in every translation unit that imports a module. Macro definitions can, however, be exported with the intentionally-ugly #__export_macro__ directive. Implement this feature by not even bothering to serialize non-exported macros to a module, because clients of that module need not (should not) know that these macros even exist. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138943 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-01When defining the implicit move assignment operator, don't performDouglas Gregor
semantic analysis when taking the address of an xvalue. Instead, just build the unary operator directly, since it's safe to do so (from the IRgen and AST perspectives) for any glvalue. Fixes PR10822. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138935 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Support importing of ObjC categories from modules.Argyrios Kyrtzidis
The initial incentive was to fix a crash when PCH chaining categories to an interface, but the fix was done in the "modules way" that I hear is popular with the kids these days. Each module stores the local chain of categories and we combine them when the interface is loaded. We also warn if non-dependent modules introduce duplicate named categories. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138926 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-31Create a CaretDiagnostic class to hold the logic for emittingChandler Carruth
(unsurprisingly) caret diagnostics. This is designed to bring some organization to the monstrous EmitCaretDiagnostic function, and allow factoring it more easily and with less mindless parameter passing. Currently this just lifts the existing function into a method, and splits off the obviously invariant arguments to be class members. No functionality is changed, and there are still lots of warts to let existing code continue functioning as-is. Definitely WIP, more cleanups to follow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138921 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-31objective-c - This patch buffers method implementations Fariborz Jahanian
and does the Sema on their body after the entire class/category @implementation is seen. This change allows messaging of forward private methods, as well as, access to synthesized ivars of properties with foward synthesize declarations; among others. In effect, this patch removes several restrictions placed on objective-c due to in-place semantics processing of methods.

2011-08-31Improve the diagnostic text for -Wmissing-noreturn to include the nameChandler Carruth
of the function in question when applicable (that is, not for blocks). Patch by Joerg Sonnenberger with some stylistic tweaks by me. When discussing this weth Joerg, streaming the decl directly into the diagnostic didn't work because we have a pointer-to-const, and the overload doesn't accept such. In order to make my style tweaks to the patch, I first changed the overload to accept a pointer-to-const, and then changed the diagnostic printing layer to also use a pointer-to-const, cleaning up a gross line of code along the way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138854 91177308-0d34-0410-b5e6-96231b3b80d8

suppress it in system headers. And it is not a good idea to suppress it in system headers. (This was originally changed in r134996 to implement -MG.) Fixes <rdar://10041960>.

sure that all of the CXXConversionDecls go into the same bucket. Otherwise, name lookup might not find them all. Fixes <rdar://problem/10041960>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138824 91177308-0d34-0410-b5e6-96231b3b80d8
